Work has now begun on the bespoke fit out, with staff said to be eagerly anticipating moving into the new facility.

Aberdeen City Council co-leader Douglas Lumsden welcomed the news the NHS will move to the city centre development.

He said: “It’s good that another tenant has been confirmed and it will add to the vibrancy of what we are trying to create in the city centre.”

NSS provides support and advice to NHS Scotland to help deliver services more efficiently and effectively.

Stephen Turner, regional director, Scotland, at Muse Developments, said: “Marischal Square welcoming another prestigious tenant further enhances the development which is revitalising the east end of the city centre.

“With additional office occupiers set to be announced in the coming weeks and five of seven retail spaces occupied, we believe Marischal Square is delivering for everyone involved.”

NSS is expected to begin transferring staff in early December once the fit out in 1MSq is complete.
